This invention relates toimprovements in atomizers and has for its principal object to provide a device thatis particularly Aadaqnted to be used for spraying either the throat Q1 the nose with a. medicament underpressure.

numerals are employed to designate like parts throughout the same: Y

' vThe hott'omof thespherical..container1 is proi'ided With an outlet neck 10 from which extends a discharge pipe 11, said pipe extending horizontally." Theinnerendportionof the pipe is curved upwardly 'and isdetaclr ably secured to the outlet neck 10 hyasui-tahle coupling shown at 12 in Figsl and AThe .outerl end ofvthe horizontally disposedpipe 11`is connected to onefendof the pipel?)v that extends kfrom the inner endet1 the substantially` oval-shaped vatomizing chamber 141, Which chamber is open Aat its forwardcnd anda cap l5 is slidahly fitted over Vtheopen Y .zforward vend portion of the atomiwzing charn-v ber in the manner' as shownin Figs l and 6. The forward "end of the pipe 13 is" formed with arestricted liquid discharge orifice 16 with which cooperates thepointed'end'of a needle valve 17 ,that is adjustable through the central portion ofthe cap 15 and extendsinto the atoinizing chamber 14;-as `also shown very .clearly in Fig. outer' endjpo'rtion of suitable implement toV facilitatev turning of Vthe needleva-lve 17 is enlarged and threaded as shown at 18 and the central portion of the cap 1 5 is formed with a conical-shaped,raised j portion 19 on the inner side thereof through 75 Vwhich the threaded portion 18 extends.

An internally and externally threaded neckv v2O is formed on the Y outer face of the ,central portion of the cap k15 through which. the Y threaded portion 18 o flthe needle valver17 also extends `and Aa iemovable cap 21 is threaded on the neck 20'.`V

The outer end of the needle valve 17 is formed with a kerf shown at 22 toaccommodate a the needle valve in order to adjustthe pointed l endtlifereof Yu'ith'iespect to the discharge ori,-

11ice16- wherebyto'` regulate the how of the vfluid under pressure from the discharge pipe 11 and 13 to the atomizing-` chamber 14.

As clearly shown in Figs. 4 and 7, the' inner end of the oval-,shapedatoinizing chainber14 is' formed witha series of airholes 23 vso that the fluid that-enters the atomizing'chainber will become oo -mingled with the air that ,enters the v.chamber 14 through the airholes A pair of discharge nipples 24 andV 25 are "i a e'xible tube shown at 26 in the dotted lines in Fig. .1 is employed, the inner end thereof V beingformed with branchpipes or stems 27 and 28 that detachably engage over the nipgples 24 and 25. Ainozzle 29 is arranged on the outer end of the tube 26 for insertion upwardly in the nostril. t -Also forming a salient part of the. present invention is the spring pressed valve that normally cuts offtlie supply ofthe medicine fromthe chamber or receptacle 1 through .the

Qatom'izing chamber 14. VThis valve comprises a' verticallylslidable vstern 30 arranged for slidable movement through the intermediate f portion of the pipe' 13. VVThe intermediate portion of the stem is formed with an opening A 31k Vthat is adaptedto have communication with the bore of the pipe 13, it being understood-ofcoursejthat a portion of the pipe in which the valve stem is mounted is-sliglitly enlarged. VA push button32 is arrangedon Vvthe upper end of the stein 30, while a stop forming plate 33 is carried by-tlie lower end 'of the stem. ',An expansible coil spring 34 encircles the upper portion of the stem and ris disposed between the -puSlibutton 32 and @the top of the pipe 13 for normally holding l'the stem in its raised'position so that the plate Y or disc 33 is held against thepipe and the opening 31 is maintained out ofl engagement for communication with the bore of said pipe .When -in use, the push button 32 is depressed whereupon the stem 3() moves downwardly through the pipe 13 so as to bring'the tion with the bore of thepipe'and Viii this manner, the Yfluidunder vpressure' will how from `the f receptacle V1 into 'the atomizing nipples in the' manner as heretofore degscribed. As soon as the pressure is taken oi'l of the push button, the spring 34j will return thelvalve toV its normally closed position thereby cutting olf further supply ofthe fluid under pressur'e'to the atomizin-g chamber.

' Itwillthus be seen Vfrom the foregoing description, that I'have provided an atomizer 'that will at all timesrbe efficient and4 reliable in its operation, and'furthermore' the parts are 'so constructed as to permitthesanie to readily and easily assembled or disassembled whenever necessary.
